A group of olive oil producing co-operatives decided to create the Priorat Olive Growers Association in 2002. (AOP). The association is aimed at improving the quality of the raw product, the production process and the distribution and sales of Priorat olive oil.

Geological characteristics, limestone soils, slate-based soils and granite, coupled with extreme temperatures (hot summers and cold winters) are all favourable factors for the cultivation of the olive tree.
